Abstract
A build plate for a three-dimensional printer includes a rigid, optically transparent, gas-permeable planar base having an upper surface and an opposing lower surface; a gas permeable adhesive layer on the base upper surface; and a flexible, optically transparent, gas-permeable sheet having upper and lower surfaces, the upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned on the adhesive layer opposite the base.
